Very light, initial impression:
The EA community is at least somewhat intellectually diverse, and on this particular topic I think there are probably some people in the EA community who may be quite sympathetic to the idea. I'll add the important caveat, though, that I merely skimmed the abstracts/introductions for those links, so I don't know exactly what all he argues for. If he is simply saying "nature is an important factor in health, economic inputs/resources, leisure, etc." then that does not sound so model-shattering. Still, I am a bit skeptical of any kind of "Here's this one thing [especially something associated with lots of sentiment/political buzz, like "nature"] that economists have inexplicably left out of their models, and it changes everything"--e.g., skeptical of its significance in general, skeptical that economists have truly left it out of their models if it is significant, skeptical that there isn't a valid reason to leave it out of their models if they have been doing that and it is significant, and so on.
Short answer: Yes. FWIW, Partha is the Chair of CSER (Centre for the Study of Existential Risk) which has, or has had, quite a few EA-sympathetic people in it. I have no idea how widely he is known across EA more broadly.
I was under the impression CSER was pretty "core EA"! Certainly I'd expect most highly engaged EAs to have heard of them, and there aren't that many people working on x-risk anywhere.
(Disclaimer: am co-director of CSER): EA is a strong influence at CSER, but one of a number. At a guess, I'd say maybe a third to a half of people actively engage with EA/EA-led projects (some ambiguity based on how you define), but a lot are coming from other academic backgrounds relevant to GCR and working in broader GCR contexts, and there's no expectation or requirement to be invoved with EA. We aim to be a broad church in this regard.
Among our senior advisers/board, folks like Martin Rees and Jaan Tallinn engage more actively with EA. There's been little Partha/EA engagement to my knowledge. (At least some of the conversations that would ultimately lead to there being a CSER predated EA's existence). I think I'd agree with comments elsewhere that Partha's work on biodiversity loss might be considered a lower priority through an EA lens than through some other lenses (e.g. ones that place 'intrinsic value of biological diversity/ecosystem preservation' more highly, or ones that place higher weight on sub-existential catastrophes or systemic vulnerabilities) although I'm glad to see it considered through an EA lens and will be interested to see EA perspectives on it.
I'm not sure how to assess what counts as 'core EA'! But I don't think the org bills itself as EA, or that the overwhelming majority of its staff self-identify as EAs (cf. the way the staff at, um, CEA probably do...)
Interesting, thanks!
